You and I get up. Oman's boring, boring. (9)
I believe the answer is:
wearisome
'boring' is the definition.
('wearisome' can be a synonym of 'boring')
'you and i get up oman's boring' is the wordplay.
'you and i' becomes 'we'.
'get up' becomes 'arise' ('arise' can be a synonym of 'get up').
'oman' becomes 'om' (abbreviation for Oman).
'boring' is an insertion indicator (some letters must 'bore' a hole into other letters).
'arise' going around 'om' is 'arisome'.
'we'+'arisome'='WEARISOME'
(Other definitions for wearisome that I've seen before include "Vexatious" , "Trying" , "Boring" , "pestilential" , "Tedious, tiring" .)
